Buck would eventually lose the North division from gambling. It is unknown how far these branches are from the Arlen headquarters, though Buck has said that North is in "charcoal country" which he thinks is the reason for the low sales numbers at that branch.
The company has five branch offices in Texas, known as Strickland Propane, Strickland North, South, East, and West. Strickland sells propane and propane accessories, including grills such as the Vogner Char-King, Char-King Imperiale and Vogner Citizen, which are showcased during the annual "Grillstravaganza" sale. Sometimes Buck is seen at Strickland headquarters, but he spends much of his time with his mistresses and otherwise enjoying himself around town. Buck Strickland runs the company, headquartered at 135 Los Gatos Road in Arlen, Texas, though he delegates most of the day-to-day responsibilities to his 41-time employee of the month, senior assistant manager Hank Hill. Strickland Propane is a fictional propane and propane accessories supplier in the animated series King of the Hill.
